Acadia still used the "old" arch/ppc bootm commands for booting
Linux images without FDT. This patch now enables these fdt-aware
boot commands for Acadia as well.

We should make sure to clear MSR[ME, CE, DE] when we boot an OS image
since we have changed the exception vectors and the OSes vectors might
not be setup we should avoid async interrupts at all costs.

The MPC8536E is capable of booting form NAND/eSDHC/eSPI, this patch
implements these three bootup methods in a unified way - all of these
use the general cpu/mpc85xx/start.S, and load the main image to L2SRAM
which lets us use the SPD to initialize the SDRAM.
For all three bootup methods, the bootup process can be divided into two
stages: the first stage will initialize the corresponding controller,
configure the L2SRAM, then copy the second stage image to L2SRAM and
jump to it. The second stage image is just like the general U-Boot image
to configure all the hardware and boot up to U-Boot command line.
When boot from NAND, the eLBC controller will first load the first stage
image to internal 4K RAM buffer because it's also stored on the NAND
flash. The first stage image, also call 4K NAND loader, will initialize
the L2SRAM, load the second stage image to L2SRAM and jump to it. The 4K
NAND loader's code comes from the corresponding nand_spl directory, along
with the code twisted by CONFIG_NAND_SPL.
When boot from eSDHC/eSPI, there's no such a first stage image because
the CPU ROM code does the same work. It will initialize the L2SRAM
according to the config addr/word pairs on the fixed address and
initialize the eSDHC/eSPI controller, then load the second stage image
to L2SRAM and jump to it.
The macro CONFIG_SYS_RAMBOOT is used to control the code to produce the
second stage image for all different bootup methods. It's set in the
board config file when one of the bootup methods above is selected.

If we move some of the functions in tlb.c around we need less

We can pack the initial tlb_table in MAS register format and use
write_tlb to set things up. This savings can be helpful for NAND
style first stage boot loaders.

Factor out the code we use to actually write a tlb entry.
set_tlb is a logical view of the TLB while write_tlb is a low level

The standard netcat, while ubiquitous, doesn't handle broadcast udp packets
properly. The local ncb util does however. So if ncb can be located in
the standard locations, automatically use that instead.
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
The netcat utility likes to exit when it receives an empty packet (as it
thinks this means EOF). This can easily occur when working with command
line editing as this behavior will be triggered when using backspace. Or
with tabs and command line completion. So create two netcat processes -
one to only listen (and put it into a loop), and one to do the sending.
Once the user quits the transmitting netcat, the listening one will be
killed automatically.

This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:
- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines
Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.
